Review Comment:
if we do not change this code, it will load all column infos of the table
which match dbzConfig.getTableFilters().dataCollectionFilter(), In my scene,
test\.t_(.*) will match 700+ tables，each chunk will load a table schema, but
will load 700+ table info, it will load almost 700x700 times. in actually ,it
should load current context tableId enough
